I can foresee in the future that I am going to need a more powerful PSU. Or am I wrong? Ultimately I intend to be driving 5 displays, all 5 having their own power supply. But my additional fan and the Radeon 9800 Pro AND my two SATA drives are drawing power from splitter cables. I also intend to try a mod at some point to have a second optical drive (replacing the ZIP drive). So can the stock PSU handle all this or am I going to need something more powerful? And if so, what will fit? Do the later model Quicksilvers have a more powerful PSU and would they fit? My objective would be to find a PSU where I don't have to modify anything.
